Guides
Buy a central vacuum in this order: check for pipe, size to your longest run, pick bagged or bagless, match the hose to your inlets, then the powerhead.
Basics8 minA central vacuum pulls air through the hose and 2-inch pipe to a motor in the garage, drops dirt in a canister, and exhausts the air. The path, step by step.
Buying7 minSize a central vacuum by the longest pipe run plus hose length, then floor area, floors, and inlet count. The furthest-corner method with a worked example.
Basics9 minOpen the inlet door and look: two small contacts means low-voltage, extra pin holes or slots means direct-connect electric, nothing means air-only.
Reviews
A strong, quiet hybrid unit for large homes, with a long parts warranty and a big canister that stretches the time between emptying.
A capable sealed-HEPA hybrid for mid-size homes, but discontinued, with conflicting warranty terms and an unclear support path after the move to Drainvac.
The most powerful unit in OVO's residential line, built for very large homes and long pipe runs; the trade is a higher noise rating than its siblings.
